v According to one aspect of the invention, there is provided afastening member for anchoring a railway rail, comprising :a length ofresilient metal of rod form which has a thickness of at least 1centimetre and which is bent so asto have, progressing from one end ofthe length of metal: to the other, a first portion which constitutes asubstantially straight leg, then a second portion in the form of areverse bend, then a third portion extending generally in the directionof said one end, then a fourth portion which extends from the thirdportion, generally to that side thereof upon which said leg is disposed,and constitutes a reverse-bend having a radius of curvature much largerthan that of the second portion, and finally a fifth portion extendingin the general direction towards the junction between the first andsecond portions.

vAccording to another aspect of the invention there is provided, incombination, a railway rail, a flange at the base of the rail, a fixedanchorage member disposed adjacent the rail, portions of said anchoragemember defining a passage which extends alongside the rail, parallel .tothe length of the rail, and is closed at the top and open at least at'one end, a fixed, unyielding surface which, as seen from the rail, isdisposed outward of said passage, and a fastening member, according tothe last foregoing paragraph, having the first portion thereof insertedin said one end of the passage and the third and fifth portions bearingone upon the top of the rail flange and the other upon said surface.

For a better understanding of the invention and to show how the same maybe carried into effect, reference will now be made to the accompanyingdrawing in which:

FIGURE 1 is a View, in elevation, of a railway rail and anchoring meanstherefor, the view being taken in the direction of the length of therail,

FIGURE 2 is a plan view of the parts shown in FIG- URE l, and,

FIGURE 3 is a side view, as seen from the right, of FIGURE 2.

In the drawings, a rail 1 has a flange 2 which is seated between a pairof ribs 3 forming part of a base plate. The latter is secured to asleeper (not shown), for example by means of screws or spikes passingthrough holes 5 in the base plate.

The base plate is made of sheet material and the ribs 3 are formed bybending the sheet material. It is apparent from the drawings thatbeneath the ribs 3 are formed passages 6 which are open at both ends andextend alongside the rail and parallel with the length of the rail.

Also illustrated are two identical fastening members, each consisting ofa bent length of so-called rod iron which, as is well known, ispreferably in fact steel. Each fastening member can be regarded asconsisting of five portions which succeed one another along the lengththereof. These five portions are:

(1) A first portion which constitutes a straight leg 7 extending fromthe end marked 10 in FIGURE 2 to about the position of the dotted linemarked 11.

(2) A second portion which constitutes a reverse bend 12 extending fromthe end of the leg 7 (at about the line States P e t 3,064,716 CPatented Oct. 17, 1961 11) to about the position of the line marked 13in FIG- adopted.

(3) A third portion 9 which extends generally in the direction of theend 10 of the leg 7, that is to say generally downwardly as seen inFIGURE 2 (on the righthand side of the rail). This third portion extendsfrom about the position of the line marked 13 to about the position ofthe line marked 14. The portion 9 in the illustrated example appears,when viewed as in FIGURE 2, to be straight and parallel to the leg 7,but the illustrated degree of proximity to the truly straight conditionand the truly parallel relationship is not essential.

(4) A fourth portion 15 which extends from about the position of theline marked 14 to about the position of the line marked 16. The portion15 extends generally to that side of the portion 9 upon which the leg 7is situated, that is to say it extends generally to the right(considering the fastening member shown to the right of the rail inFIGURE 2), as distinct from extending to the left or purely upwardly ordownwardly. The portion 15, as is apparent from FIGURE 1, does in factlead slightly upwardly and then downwardly, as it extends laterally fromthe portion 9, in order to leave adequate space between the part 15 andthe leg 7 for the latter to be'fitted in the passage 6 in the manner tobe described.

(5) A fifth portion 8 which extends in the general direction of thejunction (line 11) between the leg 7 and the portion 12. This is not tobe taken as meaning that the portion 8 must point directly to the line11 but that the portion 8 extends generally upwardly when viewed as inFIGURE 2. In the illustrated example, when the portion 8 is viewed inplan, it appears to be straight and parallel to the leg 7, but theillustrated degree of proximity to the truly straight condition and thetruly parallel relationship is not essential. The radius of curvature ofthe reverse-bend portion 15 is greater than that of the reverse-bendportion 12, with the result that, considering the right-hand half ofFIGURE 2, the portion 15 crosses the leg 17 and the portion 8 isconsequently to the right of the leg 7.

In assembling the illustrated parts, the leg 7 of one fastening memberis inserted in one end of one of the passages 6 and the leg 7 of theother fastening member is inserted in the opposite end of the otherpassage 6 so that the free ends of the two legs 7 extend in oppositedirections. The two fastening members are driven home by hammering atthe portions 12, whereupon each portion 9 will bear upon the top of theflange 2 and each portion 8 will bear very firmly upon the top of thebase plate, which affords a fixed, unyielding surface outward of theadjacent passage 6, as seen from the rail. The fastening member will actas a lever having its fulcrum extending along the axis of the leg 7 andit will be appreciated that both upward and longitudinal movement of therail will be resisted.

Instead of adopting the illustrated construction, the base plate couldbe dispensed with and the ribs 3 and passages 6 could be formed in thesleeper itself. The passages 6, in all cases, must be closed at the top,that is to say it must be impossible for the legs 7 to move upwardly.The fastening members described above will be made from metal rod havinga thickness or diameter of at least 1 centimetre.
